Qlik set analysis, partial selection of a field through modifier while ignoring the same fields selection

Question

I have fields, score, month, region and area. I need some of the score for maximum month. But my selection boxes have month, area and region. On selection of month box the value changes although in modifier I have specified month to max month variable. Sum(1<month={"$maxmonth"},region=p(region),area=p(area)>score) It still changes value when I select some other month.

Answer 3
